105,159 rounded to the nearest ten thousand

The nearest ten thousand of the provided number is 110,000.

Step-by-step explanation:

Consider the provided number 105,159

The rule of rounding a number is:

If 0, 1, 2, 3, or 4 follow the number, then no need to change the rounding digit.

If 5, 6, 7, 8, or 9 follow the number, then rounding digit rounds up by one number.

Here, we need to round the number to the nearest ten thousand.

So look at the number at Thousands place and follow the above rule.

Since the number at Thousands place is 5 so to round up the number increase the digit of ten thousand place by 1.

The digit at the ten thousand place is 0 so increase it by 1.

Thus, the number can be rounded to the nearest ten thousand is shown as: 110,000

The nearest ten thousand of the provided number is 110,000.

step-by-step explanation:

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is           symmetric about the line y = 120,000.

step-by-step explanation:

given that megan owns a clothing boutique.

the profits of 2010, 11, are recorded and shown as follows:

years since     2010 0     1     2     3       4       5

profits made in 1000's   39       84     111     120   111     84

we find that profit gradually increases form 2010 to 2013 upto 120,   then starts decreasing.

the profits for 2012 and 2014 are the same while that of 2011 and 2015 are also the same.

this shows that there is symmetry about the line profit = 120000

hence answer is:

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is           symmetric about the line y = 120,000.
